Unterschiede zwischen selbsttragenden Satteltankanhängern und Vollrahmenanhängern
Self-supporting saddle tank trailers and full frame trailers are two different types of construction, each with specific advantages and disadvantages. Here are the most important differences:
Self-supporting saddle tank trailers SEKA trade name SPSTT
Saddle tank trailer with full frame made of KTL-coated
fine-grained steel in standard design
1. Construction
- Definition: In self-supporting saddle tank trailers, the tank itself is the load-bearing element. The structure of the tank supports the entire load and the forces that occur during transport.
- Advantages:
- Better use of space, as the space in the trailer can be used more efficiently.
- Less material usage
- Disadvantages:
- Limited flexibility for modification or repair, as the tank and support structure are one.
- Increased weight due to the additional tank structure
- Possibly lower stability under extreme loads or uneven road conditions compared to frame constructions.
- Higher manufacturing costs and material prices
The Stella 105 saddle tank trailer is a tank semi-trailer with the tank mounted on a full frame.
1. Construction
- Definition: Full frame trailers have a separate, load-bearing frame structure that supports the load of the tank and the components mounted on it.
- Advantages:
- Lower weight, as no separate tank structure is required.
- Greater stability and strength, which increases safety under high loads.
- Flexibility in adapting or modifying the trailer, as the tank is not directly part of the supporting structure.
- Better distribution of forces, which can extend the service life of the trailer.
- Disadvantages:
- Service intervals are more intensive but easier
2. Maintenance and repair
- Self-supporting saddle tank trailers:
- Maintenance can be difficult because the structure of the tank and its load-bearing capacity are closely linked. Damage to the tank can affect the entire structure.
- Full frame trailer:
- Maintenance and repairs are generally easier, as the frame structure is independent of the tank. Damage to the tank can often be localised and repaired without affecting the entire structure.
3. Economic efficiency
- Self-supporting saddle tank trailers:
- Higher acquisition costs due to the additional tank structure, but potentially lower maintenance costs and longer service life can offset the higher initial investment.
- Full frame trailer:
- Generally less expensive to manufacture as less material is required and the weight is reduced
Conclusion
The choice between self-supporting saddle tank trailers and full-frame trailers depends heavily on the specific requirements of the application:
- Self-supporting saddle tank trailers offer advantages in terms of weight and space utilisation, while full-frame trailers offer greater stability and flexibility.
- The decision should take into account the type of medium to be transported, the required safety, economic efficiency and maintenance requirements.
